Control transforMer ConneCtions (non-uPs)
Connect the AC input power to the control transformer
according to the following procedure.
1. Ensure that the primary tap on the control
transformer matches the line voltage and
frequency connected to the gate operator.
2. Measure the line voltage carefully to distinguish
between 208V and 230V branch circuits.
NOTE: A label on the transformer top identies the
various voltage taps available.
3. Use wire nuts or crimp-connectors to connect
the power input conductors to the applicable
taps on the Control Transformer.
Gate oPerator ConneCtions (Modular unit)
If you have the modular unit, additional conduit is needed to house the hydraulic hoses and electrical wiring.
You need a 2-inch (5 cm) diameter conduit for hydraulic hoses and a ¾-inch (19 mm) conduit for electrical
wiring. AC input power is connected to the hydraulic pump and electrical components enclosure
(HydraSupply).
A supplemental manual, provided with the product, describes the installation overview, wiring and conduit
considerations.

* Variable Frequency (VF) or 2 hp gate operators:
Never connect to the white 120V wire. Make sure the
connection wires match the voltage found on the operator’s nameplate.
